LooK-,i-mxioeI SPECIPICATION forming part of Letters Patent No. 390,418,ated October 2, 1888.

Application filcd December 23, 1887. Serial No. 258,810. (No model.)

;To ctZZ 107mm it may concern:

Be it known that I, LEONARD TIL'roN, of the city of Brooklyn, in thecounty of Kings and State of New York, have invented a new and ImprovedFastener for Vindow-Blinds, of which the following is a full, clear, andeX- act description.

Referenceis to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicateeorresponding parts in both the figures.

Figure 1 is a perspective view of a windowblind having niy inventionapplied thereto, and Fig. 2 is a detailed sectional view of the same.

The invention willfirst be described in connection with the drawings,and then pointcd out in the claim.

A represents the window-frame,'to which the window-blind B is secured bythe hinges B' B', in the nsual nianner. To the outside of the frame A.is securcd, by screws or other fastenings, a a, the casting C, whichcomprises the Vertical plate d and the horizontal plate d', which latteris slotted at d2 to receive the vertical bolt D, which may be held byany suitable means, preferably by the collar f and nut f'. (Shown inFig. 2.) Upon the bolt D and resting upon the collar f is pivoted thearni E, which reaches along the blind and is connected at its outer endto the blind by the clip E' and pin e, as shown clearly in Fig. 1. Thearm E is provided at its pivot with the circn'- lar rack F. This is bypreference made in a separate piece and secured to the said arm E by ascrew, c. (Shown in Fig. 2.) The rack F is for receiving the outer endof the bolt G for looking the window-bli nd wholly open or closed or atany desired intermediate position. The said bolt G passes through anopening, g, in the window-frame A, and -also through the fianged andtubular castingh, secured to the inside of the frame A, and upon theinner end of the bolt is secured the knob g', by which the said bolt maybe conveniently drawn inward against the tension of the spring J fordisengaging its outer end from the rack F, so that the position of theblind may be changed. The spring acts between the casting h and the head'i formed upon the bolt G, so that it normally presses the bolt forwardto engage the said head 'i with the teeth of the rack F.

Having thus described niy invention, what I claim as new, and dcsire tosecure by Letters Patent, is-

The casting O, comprising the Vertical plate d and horizontal plate d',slotted at (12, in combination with the pivot-bolt D, held in said slot,the arm E and rack F, and the lookingbolt G, held in an aperture in thewindowfrarne A, substantially as dcscribed.
